Lower Bound of Multipartite Concurrence Based on Sub-quantum State Decomposition
arXiv:1208.1745 · doi:10.1103/PhysRevA.86.022307
Abstract
We study the entanglement of tripartite quantum states and provide analytical lower bound of concurrence in terms of the concurrence of sub-states. The lower bound may improve all the existing lower bounds of concurrence. The approach is generalized to arbitrary dimensional multipartite systems.
